I have an app which works perfect in all 4.x devices, but now I have a report of the app not working on a samsung_gt (advance) android 2.3.6. Here is the trace:

我有最新的支持 jar (v4) 并且已经修补了 gson 库，以防手机已经在使用它.问题似乎是支持库.有任何想法吗?非常感谢！

I have the latest support jar (v4) and have already patched the gson library in case the phone is already using it. The problem seems to be the the support lib. Any ideas? Thank you very much!

推荐答案

java.lang.VerifyError 的最常见原因是有一个类使用了 Android 版本上不可用的方法应用运行的位置.

The most common cause of java.lang.VerifyError is having a class that uses methods that are not available on the version of Android where the app is running.

根据您的堆栈跟踪，com.bamobile.fdtks.activities.MainActivity 似乎使用了一种在 Android 2.3.6 上不可用的方法，因此您的验证错误"重见天日.

Based on your stacktrace, it seems that com.bamobile.fdtks.activities.MainActivity is using a method that is not available on Android 2.3.6, hence the "verification error" that you're seeing.

要修复它，请将您的应用的 minSdkVersion 和 9 或 10 (Android 2.3.6) 和查找错误/有关该版本 Android 不受支持的方法的警告.您还可以(临时)将 minSdkVersion 和 targetSdkVersion 更改为 9 以在您使用 Gingerbread 中找不到的方法时强制编译器失败设备.

To fix it, change the minSdkVersion and of your app to 9 or 10 (Android 2.3.6) and look for errors/warnings about unsupported methods for that version of Android. You can also change (temporarily) both minSdkVersion and targetSdkVersion to 9 to force the compiler to fail when you use methods that are not found in Gingerbread devices.
